The Carolingian Empire
Just as in the Byzantine and Islamic worlds, in Europe the period from 750 to 1050 saw first the formation of a strong empire, ruled by one man, and then its fragmentation as local rulers took power into their own hands. A new dynasty, the Carolingian, came to rule in the Frankish kingdom at almost the very moment (c. 750) that the Abbasids gained the caliphate. Charlemagne, the most powerful Carolingian monarch, conquered new territory, took the title of emperor, and presided over a revival of Christian classical culture known as the Carolingian renaissance. He ruled at the local level through counts and other military men. Nevertheless, the unity of the Carolingian Empire—based largely on conquest, a measure of prosperity, and personal allegiance to Charlemagne—was shaky. Its weaknesses were exacerbated by attacks from Viking, Muslim, and Magyar invaders. Charlemagne’s successors divided his empire among themselves and saw it divided further as local leaders took defense—and rule—into their own hands.
